A Modified Newtonian Quantum Gravity Theory Derived from Heisenberg's Uncertainty Principle that Predicts the Same Bending of Light as GR

Mike McCulloch has derived Newton's gravity from Heisenberg's uncertainty principle in a very interesting way that we think makes great sense. In our view, it also shows that gravity, even at the cosmic (macroscopic) scale, is related to the Planck scale. Inspired by McCulloch, in this paper we are using his approach to the derivation to take another step forward and show that the gravitational constant is not always the same, depending on whether we are dealing with light and matter, or matter against matter. Based on certain key concepts of the photon, combined with Heisenberg's uncertainty principle, we get a gravitational constant that is twice that of Newton's when we are working with gravity between matter and light, and we get the (normal) Newtonian gravitational constant when we are working with matter against matter. This leads to a very simple theory of quantum gravity that gives the correct prediction on bending of light, i.e. the same as the General Relativity theory does, which is a value twice that of Newton's prediction. One of the main reasons the theory of GR has surpassed Newton's theory of gravitation is because Newton's theory predicts a bending of light that is not consistent with experiments.
